The lower rocker panel wide sill moldings (Option code M25) are no longer available and neither are the plastic retainer clips (p/n 6002437).
However the wide sill moldings for a '71-'74 Dart/Duster are being reproduced, however they are about 1" too long, so they have to be shortened to fit - which is no problem.
I found some retainer clips p/n 6003775 that looked like they would work, but they are too wide.
In the end I decided to simply glue them in place using polyurethane adhesive. I first installed blind well nuts and crimped them in place, then screwed on small pieces of aluminum, followed by a dob of adhesive on each one. Looks like it should work OK.
